Hello dear volvo community. Well, after having been proud and satisfied S40 ll d5 (bj 08) for 1, 5 years, I have a problem for the first time. I saw by chance that my coolant tank is only barely filled. Say: very far below minimum, about 1-2 cm from the visible container bottom. I then tilted coolant afterwards. After I drove about 20 km I looked in again and determined that the liquid is again at this place, however, the container does not get completely empty. After a look under the car I found a drop in irregular short distances. Approximately at height medium console. Can you only see Thursday to the workshop. Do you have any idea what this could be? Even a known weak spot? The BC does not give out any fault and the car has now 56tkm down. Thanks already to the stef.
